ARTHUR HARRY HARVEY, OF DUNBAE, PENNSYLVANIA.

AUTOMOBILE RADIATOR CAP.

Application filed November To all whom it may concern:

Be it known thatl, ARTHUR H. HARVEY, a citizen of the United States, residing at Dunbar, in the count 1 of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Automobile Radiator Caps, of which the following is a specification.

My invention relates to an improvement in automobile radiator caps.

The object is to facilitate pouring water in the radiator, and, incidentally, to provide an attachment that can be easily applied or removed, and that will be ornamental in appearance, and also form a support for any type of motometer attachment, such as the Boyce or other device of that character for indicating the motor heat.

This invention consists in a shell constructed and adapted to screw into the headblock of the radiator, the upper portion having the function of a funnel tapering toward the ends of the upper edge, curved more or less to conform to the shape of a water bucket, and a lid hinged at one end to one end of the shell and adapted, when closed, to fit tightly the upper edge of the shell, and having a hollow boss at the center which pinches between it and a seat in the center of the shell the soft rubber gasket, in order to make a waterand steam-tight joint, and the free end of the lid adapted to be fastened by friction or spring or other means, whereby to hold the lid down.

In the accompanying drawings:

Fig. 1 is a plan view;

Fig. 2 is a longitudinal section on line A-A of Fig. 1, the lid also being shown in its raised position in dotted lines;

Fig. 3 is a fragmentary section on line AA but showing the screw threads inside, instead of outside;

Fig. 4 is a transverse section on line 13-13;

Fig. 5 is a section on line CC;

Fig. 6 is a detail showing a slight modification.

A, represents the hollow shell. having a screw-threaded collar 1 at the center. This may have the threads outside. as shown in Fig. 2, or inside, as shown in Fig. 3, whereby it is screwed in position at the top of the radiator. The ends 2 of the shell extend outwardly and upwardly in opposite directions, and preferably taper slightly, and the upper edge 3 (shown in dotted lines in Fig.

25, 1921. Serial N0. 517,663.

2) has a curvature adapted to conform to the curve of a water pail or bucket.

Thus the shell A, withits tapering ends 2, forms a funnel leading to the collar 1, and thence into the radiator to facilitate filling the latter.

A lid 4: is connected to one end of the shell by hinge B at one, and by a frictioncatch 6 at the other end, as shown in F ig. 2, or by a spring-catch 7, if preferred, as shown in Fig. 6. This lid is curved to conform to and fit the upper edge of the shell, as clearly shown in Figs. 2 and 6, and its edges interlock therewith as illustrated in Fi 5.

it the center of the lid, a depending inverted cup 5 is formed integral therewith, the lower edge thereof receiving and pinching between it and the seat 6 a soft rubber gasket 7, whereby a waterand steam-tight joint is formed to prevent water or steam from the radiator from escaping therefrom.

It will be seen when the lid is closed that a perfect joint is formed at the center, and the catch 6 or 7 or any other form, for that matter, holds the lid securely fastened; and when the catch is in the form shown in Figs. 1 and 2, of the friction type, the curvature of the lid affords the required give or spring in the lid to permit it to close and form a rigid fastening. If a motometer or other instrument is to be attached, it is done by boring a hole through the center 8 of the cap, and screwing it therein, or otherwise securing it. In this way, the motometer is taken care of, and does not have to be unscrewed or removed when the radiator is filled, as the lid forms a support for and carries the inotometer with it.

The ends of the shell afford a means for grasping it and turning it when it is screwed 111 place, or unscrewed. Furthermore, the whole appearance is ornamental and attractive so that in addition to its real utility as a funnel for facilitating the pouring of water into the radiator and as a means of support for the motometer. the device presents an attractive and ornamental appearance at the front of the car.

I claim:

1. The combination with a hollow shell constructed and adapted to screw at the center to the radiator, the ends tapering and extending upwardly with the upper edge curved, a lid hinged at one end to one end of the shell, and conforming in shape to, and

adapted to interlock with the curved upper edge of the shell, and having Ineansiat'the free end for rigidly fastening the lid in closed position, the shell having an annular seat at the center and a cup,iwhicliuco-op erates with the annular seat, and a gasket adapted to be held therebetween when the lid is closed.

2. The combination with a hollow shell constructed and adapted to screw at the center to the radiator, the ends tapering and extending upwardly with the upper edge curved, a lid hinged atone end to one end of the shell, and conforming in shape to and adapted to interlock with: the curved upper edge of the shell, and having means at the free end for rigidly fastening the lid in closed :position, theshelli having an annular seat at the center, a cup which co-operates with the annular seat and a gasket adapted to be held therebetwe'en when the lid is closed, the metal of the center of the lid adapted to be tapped and threaded to receive a motometer.

In testimony whereof I afiixmy signature.

ARTHUR HARRY. HARVEY.
